iterating over sub-matches using std::tr1::regex?

[DomoChan]

Given a repeatable group expression

([abc])+

and given its input

cab

will result in nested subgroups, which taken from 'rad software
regular expression tester' looks like

Match 'cab'
- Group 1
- c at pos 0 length 1
- a at pos 1 length 1
- b at pos 2 length 1

Id like to use the regex classes found in std::tr1 to iterate over all
the matches in Group1.

Im using regex_search to fill a smatch object. I need to go one more
step to iterate over the matches found in Group1. Can anyone tell me
what I need to do to iterate over the sub-matches?

I've tried the following, but it doesnt seem to work

// note: initialResults is sucessfully filled with a single group
match
regex_search( "cab", initialResults, "([abc])+" );

for ( size_t ii = 1; ii < initialResults.size(); ++ii )
{
ssub_match groupResults;
// note: groupResults.matches is false. groupResults.first is
NULL, as is groupResults.second
groupResults.compare( initialResults[ ii ] );
}

Thanks for any assistance!
